什么是时钟周期和时钟速度？ [英] What is a clock cycle and clock speed?

问题描述

我一直在读一本有关计算机处理器的书。我遇到了一些很难理解的术语，例如时钟刻度，时钟周期和时钟速度。如果有人可以用一种简单的语言来澄清这一点，我将非常感谢。

I have been reading a book about the Computer's Processor. And i came across some of the terms like clock Ticks, clock Cycle and Clock Speed that i am finding very difficult to understand. I will be very thankful if someone can clarify this in a simple language. Thanks in advance !

推荐答案

计算机处理器或CPU的速度由时钟周期决定。 strong>，这是振荡器的两个脉冲之间的时间量。一般而言，每秒脉冲数越高，计算机处理器将能够更快地处理信息。时钟速度以Hz为单位测量，通常为兆赫（MHz）或千兆赫（GHz）。例如，一个4GHz处理器每秒执行4,000,000,000个时钟周期。
计算机处理器可以在每个时钟周期执行一条或多条指令，具体取决于处理器的类型。早期的计算机处理器和速度较慢的处理器每个时钟周期只能执行一条指令，但是速度更快，功能更高级的处理器可以在每个时钟周期执行多个指令，从而更有效地处理数据。

The speed of a computer processor, or CPU, is determined by the Clock Cycle, which is the amount of time between two pulses of an oscillator. Generally speaking, the higher number of pulses per second, the faster the computer processor will be able to process information. The clock speed is measured in Hz, typically either megahertz (MHz) or gigahertz (GHz). For example, a 4GHz processor performs 4,000,000,000 clock cycles per second. Computer processors can execute one or more instructions per clock cycle, depending on the type of processor. Early computer processors and slower processors can only execute one instruction per clock cycle, but faster, more advanced processors can execute multiple instructions per clock cycle, processing data more efficiently.

另一方面，时钟速度（有时称为时钟频率）是指由振荡器产生的每秒脉冲数，该振荡器为处理器设置速度。时钟速度通常以MHz（兆赫兹或每秒数百万个脉冲）或GHz（千兆赫兹或每秒数十亿个脉冲）测量。当今的个人计算机以数百兆赫兹的时钟速度运行，有些甚至超过了1千兆赫兹。时钟速度由石英晶体电路确定，类似于无线电通信设备中使用的晶体。

And on other hand, Clock Speed (Sometimes called as Clock Rate) refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second). Today's personal computers run at a clock speed in the hundreds of megahertz and some exceed one gigahertz. The clock speed is determined by a quartz-crystal circuit, similar to those used in radio communications equipment.
